My invention is a combined starter switch and choke for motor vehiclesand an object of the invention is toprovide a device which will (serveas the usual'chokerod and as a circuit closer for controlling anelectrical circuit to the usual starter.

Further the invention provides a device of this character which willpermita circuit to the starter to be completed Without choking thecarbureter; permit the usual chokevalve to be adjusted to any desiredposition while the motor is in operation; and it may also be operated toactuate the choke valve to full open position prior to completion of thestarter circuit.

With the preceding and other objects and advantages in mind theinvention consists in the novel combination of elements, constructionsandarrang'ement of parts and operations to be hereinafter specificallyreferred to, claimed and illustrated in the accompanying drawingswherein;. I

Figure 1 is a fragmentary vertical section view of part of a motorvehicle with my invention associated therewith;

Fig. 2 is a longitudinal sectional view taken on line 22 of Fig. 1, thebroken lines indicating the device in full choking position; and

\ Fig. 3 is a transverse section taken on line 33 of Fig. 2;

drical casing is provided comprising a pair a cup-shaped member 7 at itsouter end. An-

nular flanges 8 are formed on each of the: g I

ing electrical "connection with" the usual starter, not shown, areconnected w th one sections and extend circumferentially around thesame.

To secure the casing'in place a plurality of bolts 9 extendinglongitudinally of the casing pass through the flanges at spacedintervals and through the usual dash board 9. Pairs of jam nuts 11 arethreaded upon'the 15 bolts and engage the opposite faces of the flanges.'Similar nuts 11 arealso threaded upon the bolts and engage the innerface of the dash board. I v

A substantially frusto-conical hood 12is arranged in longitudinalalignment with the casing and is provided with'an annular flange 13 atits inner end which is secured toy'afsimilar annular flange 14 formed ontheadj-acent end of the cup-shaped member 7 of the section 6. Aforwardly extending tubul'ar9 5 guide 15 extends from the forward end ofthe hood through which the usual choke valve operating cable 16 extends.j f f A choke rod 17 extends centrally and lon-. gitudinally through thecasing and is slid-' ably supported by the end walls of the "cupshapedmembers. One end of the choke rod extends into the hood 12 and isconnected with the cable 16 by a coil spring 18;" The opposite end ofthe choke rod passes through the dash board is equipped with theusualoperating handle 19.

a contact plateor switch member '20 isfre-Fm ceive d on the choke rod ata point within'the confines of the casing and is secured thereto byWashers 21 suitably held onthe chokerod and engaging the opposite facesof'the' t'zontact plate. j Suitable insulation 23 is provided 'forinsulating the contact plate from W er'21 and choke rod. I

A pair of spaced contacts 24 project'from theinner face "of the end wallof each oftlie cup-shaped'members 7 and are suitably ins latecl'"therefrom by insulating material I 25 Referring to the invention indetail a cylin- I which alines the cup-shapedimembers. The

contacts 24 are formed with binding posts .2 6 of tubular sections 5 and6 having telescopic '35 engagement and each of which is formed with "andare connected together in series by conductor wires27, A pair of feedWires 28 hav- Pair Of "thebinding Posts us. withitheao choke rod ineither of its extreme positions the contact plate 20 will engageonepair'of thecontacts 24 to complete an electricalcir- "cuit'throughthe starter.

With my. invention will be observed that' os the circuit to thestarter'will' be completed 7 upon longitudinal movement of the chokerodin either directiorip Thus upon forward thrust of the choke red thecircuitto the starter will be completed without choking the ca-rbureter.In choking the' carbureter the contact plate will complete the circuitsubsequent to the full choking of the carbureter. That is to say, whenthe parts reach the broken line position shown in Fig. 2 the choke valvewill have reached its full open position so that upon continuedmovementof the choke.

rod the circuit to the starter will be com- 'pleted. These operationsare possible by reason of the elastic or spring connection 18 betweenthe choke rod and cable 16.

For the purpose of retaining the choke rod against rotation so that thecontact plate 20 will always be in longitudinal alignment with thespaced contacts Qtap'airof parallel guide bars 29 are supportedlongitudinally within the casin from one of the cup-shaped mem i'bers'7.

IY'What 1s clai'med'is:

1]. In a combined choke actuating'device s particularly disclosedin'Fig.3 these guide bars 29 are located upon opposite sides of the'cho'ke rodand pass through Slot 30 in the contact plate. Thus the choke rod andcontact true longitu (plateQO will always move inja inal direction andat the same time be prevented from rotating.
